Bits of code from the Ansible Advanced - Hands-On - DevOps class I took on Udemy https://www.udemy.com/course/learn-ansible-advanced/
- Install Virtualbox and Vagrant on your host machine
- (Windows users will want to install Git as well)
- Install Vagrant plugins:
vagrant plugin install vagrant-vbguest vagrant-hostsupdater - (Windows users must give themselves modify access to the hosts file:
explorer 'C:\Windows\System32\Drivers\etc') - Iimportant Windows users: configure git line endigs as follows (from Git Bash):
git config --global core.eol lf
git config --global core.autocrlf input
- Clone this repo:
git clone https://github.com/dsnyder0pc/ansible-advanced-class.git - Change directory to the repo folder (eg.,
cd ansible-advanced-class) - run
vagrant upto launch guests
You'll start with three new virtual machines:
$ vagrant status
Current machine states:
controller running (virtualbox)
db1 running (virtualbox)
web1 running (virtualbox)
web2 running (virtualbox)
To use the controller for your Ansible work, you'll need to copy ssh keys to the other hosts. To do that, login to the controller with: ssh ansible@192.168.77.71 (or ssh ansible@controller). Password is passw0rd
Once you are logged in, run: class/copy-ssh-keys.sh
I've dropped a class symlink into the ansible user's homedir for your convenience. This provides convenient access to the invenotry and playboook files that you are working with on the host machine, presumably with a nice IDE. For this class, you'll be running ansible-playbook from the class folder on the controller host. For example (vault password is passw0rd:
ansible@controller:~$ cd class
ansible@controller:~/class$ ansible-playbook playbook-13-01.yaml -i inventory.txt --ask-vault-pass
IF there are no errors during the play, you should be able to test with curl:
$ echo $(curl -s web1:5000)
Welcome!
$ echo $(curl -s web2:5000)
Welcome!
